The process in which a natural soil is enhanced for the purpose of added stability and strength is called soil stabilization. Roadways, site development, home sites, commercial buildings and any property with sub-soil characteristics that will be used in a building application can utilize soil stabilization processes to ensure that their development is up to code.
Any project must first start with design and the design for a soil stabilization needs to involve a geotechnical engineer. A geotechnical engineer is knowledgeable about the soil density and based on what is to be placed on the surface of the soil, the geotechnical engineer will need to determine the best methods to utilize for the optimum results.
There are several techniques the geotechnical engineer may recommend. First is mechanical soil stabilization which is considered the oldest method. Through Dynamic or vibro compaction the soil is packed so that all the voids are filled. In chemical stabilization methods, additional material is added to the soil to interact with is and ultimately change the soils properties making is stronger and more stable. The newest form of soils stabilization is polymer or alternative soil stabilization. This method uses a plymer to bind with the soil creating added strength and stability. It is cheaper and more effective than mechanical soil stabilization and more eco-friendly than chemical soil stabilization.
